What are the four principle neurotransmitters important to counselors?

• A. The four principle neurotransmitters are acetylcholine, serotonin, dopamine, and GABA (gamma amino butyric acid).
• B. The four principle neurotransmitters are norepinephrine, glutamate, acetylcholine, and serotonin.
• C. The four principle neurotransmitters are dopamine, norepinephrine, serotonin, and endorphin.
• D. The four principle neurotransmitters are glycine, glutamate, GABA, and serotonin.

Answer: (A)

Four neurotransmitters most commonly highlighted for counselors are acetylcholine, serotonin, dopamine, and GABA. Acetylcholine supports learning, memory, and attention, so understanding its role helps explain how cognitive processes can be affected in aging, dementia, or therapy that targets mental functioning. Serotonin helps regulate mood, sleep, appetite, and impulse control, linking directly to mood disorders, anxiety, and eating issues that counselors frequently encounter. Dopamine is tied to motivation, reward, and reinforcement, which relates to addiction, relapse, and goal-directed behavior in therapy. GABA is the main inhibitory transmitter that calms neural activity, underpinning anxiety regulation and arousal control, a core area in many therapeutic approaches.

Other lists include neurotransmitters like norepinephrine, glutamate, glycine, or endorphins, but those four are commonly emphasized because they cover mood, cognition, reward, and inhibition in a way that aligns with typical counseling concerns and interventions.
